T o a-ZZ 'whom t may concern:

Be it known that I, THOMAS LUND, a citizen of the United States,residing at Bew erly, in the county of Essex and State of Massachusetts,have invented certain Improvements in Machines for Operating Upon Heels,of which the following descripj' tion, in connection with theaccompanying drawings, is a specification, like reference characters onthe drawings indicating like parts in the several figures.

This invention relates to machines for performing a plurality ofoperations upon heels. The invention is herein set forth by way ofillustrationv with special referenceA to its applicability tocompressing and breasting heels before they are attached to their shoes.

yUntil recently ithas been a universal practice in this country t0breast the heels of shoes after they wereattached. Now, however, thepractice of breasting heels before their attachment is becomingincreasingly prevalent. Since practically all heels, the breasts ofwhich are straight in the direction of the height of the heel, arecompressed, it is advantageous to perform the lbreastingl operation inconjunction with the compressing operation. Accordingly, an

object of this invention is to provide a ma-` chine which willautomatically compress and breast heels.

A feature of the invention consists in an organization comprising meansfor removing surplus material from a heel and compressing the heel, incombination with operating means to effect said treatments of the heelin succession. As herein shown the heel is operated upon at. successivestations, and means comprising a carrier, which may be intermittentlyrotatable, is operated in time relation to the said means to effectprogression of the heel from one to the other of said means. As is usualin well-lmown heel compressing machines, as shown, the side dies of therelatively movable heel compress# ing means move vertically, and thetoplift plate moves relatively to the compressing means to eject theheel or to cause it to be presented after compression abovethe'compressing means. To provide effective cooperation with thecompressing mechanism, the illustrated heel transferring means,

vature to the transverse herein .shown as comprising co-operatinglingers, is operated horizontally to takethe heel from the position inwhich it is presented by the toplift plate or ejector and to carry it toanother position -for another opj eration. Preferably the transferringmeans presents the heel in predetermined operative relation to a secondtransferring means which is intermittently operated and may comprise,1as shown herein, a rotatable or endless carrier having a series of pairsof jaws movable over a relatively fixed table upon which the heel islocated by the first transferring means, a pair .of jaws being closedupon the heel and moved to another' position 1n operative relation tothe breasting means which, as shown, comprises a re ciprocating knifeacting in the direction of the height of the heel. i

A further feature of the invention consists in means for automaticallylocating a shoe bottom blank, or example an unattached heel, vin apredetermined position both longitudinally and rot-ationally, that is,aboutan axis lying within the body of the blank and perpendicular to itslarger flat faces. Such means may consist in positioning membersrelatively power o erated in the operation of the machine an acting onthe blank to determine both its longi tudinal position and orientation,that is, to effect a rotational movement of the blank in its own planeso as to locate its longitudinal median line in a predetermineddirection. The blank is thus accurately located for a subsequentoperation 0n the blank and in the exemplary embodiment of the inventionillustrated a heel blank is positioned in a plane parallel to the planeof the table so that the breast face will be parallel with the knifeedge. As shown herein, the positioning means comprises a striker whichis actuated to engage the heel during operative movement of the out ofoperative position during the return movement of the knife. Preferablyand as shown, the operation of the striker is controlled by the knifeslide during the operative movement of the knife.

Another feature of the invention consists in means on the tablecorresponding in curcontour of the knife and xfeo-*operating with theknife to eiect a knife and which is held that disc =of a machineembodying shear cut upon the heel. Preferably said means is formed as ayblock which may be detached from the table when a differently curvedknife is to be used and another yblock substituted therefor whichcorresponds to the curve of the new knife. Also, as shown, the block isarrangedfor adjust-ment transversely of the knife to enable itsco-operating face to be set in accurate relation t0 the knife.

A further feature of the invention consists in novel mechanism forreleasing the intermittently movable jaws to allow them toseize the heelor to open them to allow the heel to fall out after the breastingoperation is completed. Preferably at the point where the jaws areopened to release the breasted heel the table that supports the heel iscut away to allow the heel to fall from the jaws.

Another feature of the invention consists in means for holding annnattached heel in a fixed position and means for effecting two strokesof the breasting knife while the heel is so held. The first strokebreasts the heel by making a. roughing cut while the second strokeeffects a finishing cut which Smooths the breast face.

These and other features of the invention, including .novel means forholding the heel, for controlling the opening and closing of the jaws,and various details of construction Aand combinations of'parts. willappear more fully from the following detailed description when read inconnection with the accompanying drawings and willV be pointed out inthe appended claims.

The heel compressing mechanism herein shown by way of illustration issimilar to United States No. 1,172,471, granted February 22, 1916 on myapplication.'

.In Fig. 1 of the drawings the numeral 1 indicates the rigid frame ofthe machine on which the mechanism is supported. Vertical guideways areprovided in the sides of the rigid frame and a head 2 is mounted thereinfor reciprocation. A suitable driving pulley and reducing mechanism areprovided as shown in my prior patent above referred to, for transmittingmotion to a gear 8 on a crank shaft 9. A link 10 is connected to thecrank shaft 9 and also to' a toggle composed of members 11 and 12. Thetoggle member 11 is pivoted to `a rigid portion of the frame near itsbase and the other toggle member 12 is pivoted at 14 to thereciprocating head 2. The head carries a heel mold comprising a topliftplate 40, a breast die 21, andv laterally movable side compressing dies22, as shown in Figs. 1 and 6.

In the upper part of the machine frame and alined with the recprocatinghead 2 is formed a rigid abutment 23 upon which is detachably mounted aheel seat die 25 in position to co-operate with the mold members carriedby the head 2. The side compressing'dies rest on the top of the head 2and are removably retained in slides 3() in order that other dies ofdifferent shapes may be substituted in changing from one style of heelto another. The side compressing dies 22 and breast plate 21 areactuated to close the mold and are thereafter opened to release thecompressed heel by any desired mechanism, for instance, by normallyinclined links 17 pivoted on opposite sides of the machine frame at 18,18 as shown in Fig. 6.

The toplift plate 40 is provided with a downwardly extending stem 41 andmechanism is provided such, for instance, as that shown in my priorpatent above referred to, for moving the toplift plate relativelyr tothe mold, as shown in Fig. 1, so as always to present the heel with itslower or toplift face fiush with the upper surface of the mold.

The heels are fed to the compressor at the left of Fig. 1, each heelbeing positioned between fingers 31 (Fig. 6) with its breast faceagainst a breast gage 33, the fingers being then in open position andthe mold closed. As the head 2 moves downwardly and with it a frame 35on which a lever 37 is carried. the lever 37 is actuated bv connectionsshown in Fig. 1 to move the fingers and heel over the now open mold, thefingers being separated to release the heel b v the action of astationary cam 39 acting upon an jaw opening outward projection 43 ofone of the lingers 31. This feeding mechanism is well-known 1n heelcompressors and. is substantially as shown and described in my priorpatent ed after compression by the toplift plate 40,

- will now be described and comprises mechanism best shown in Figs. 1and 6.' As shown in Fig. 6, the mold slides 30, which are connected tothe links 17 and through which pressure i's applied laterally to themold members 22, 22, are provided `with grooves 32 preferably dovetailedin which are mounted sliding blocks 34. Fingers 36 are xpivoted to theblocks at 38 and are shaped as shown in Fig. 6. To each linger, at a4point outside of the pivot 38, is'pivoted a member 42 by a verticalpivot 44. Links 46 are pivoted byA horizontal pivots 48 to the members42, and means to be described is provided for moving the links 46lengthwise to operate the lingers. The pivots 44, I48

rovide universal joint connections between the links 46 and the lingers36. Movement of the links 46 toward the heel compressor first causes thefingers 36 to separate sulii-` ciently to clear the heel and the feedfingers 31 and then moves the slides 34 with the lingers 36 lengthwiseof the vheel in the compressor until the fingers are behind the heel,the feed fingers 31 being at the same time retracted. The motion of thelinks 46 is then reversed, causing the ends 47 of the lingers' 36`toclose against the heel. Lugs 50 on the fingers then engage the breastface of the heel and further movement of the links causes the fingers totransfer the heel from the heel compressor into a predetermined positionupon a stationary table 52 which is located at the rear of thecompressor.. To control the closing movement of the lingers, screws 54are provided which are threaded through the members 42 and are adjustedto engage the outer ends of the lingers after a redetermined closingmovement of the ngers has been effected by movement of the links 46 awayfrom the compressor. The screws 54 may beso set that when the ends 47 ofthe fingers engage the sides ofthe heel being treated the screws l willlimit further movement of the fingers and prevent lateral displacementof the heel by movement of one linger farther than the other. Thisconstruction minimizes mispositioning of the heel due to vspringing orlost motion of the parts', and if the heel is in such position that onelinger engages it lirst that finger will shift the heel and position itproperly in engagement with the other finger.

At their rear ends thelinks 46 are pivot ed at 58 in the slotted ends ofa short cylindrical member 60 which is mounted to turn moves upwardlythe rod 82 fingers.

in the lower end of any arm 62 and is held from longitudinal movement bya screw 64 engaging a groove Vformed in the member 60. at its upper endthe arm 62 (Fig. 1) is integrally connected with a sleeve member 63which is rotatably mounted on a shaft 65 journaled inra frame 66 boltedto the main frame 1. On thesleeve member 63 is another arm 68 slotted at70 to receive a block 72 (Fig. 2) which is adjustable lengthwise of theslot by means of a tongue 74 attached tothe block and 'rotatablyconnected to an adjusting screw 76 threaded into the end of the arm 68.'An eye-bolt 78 passes freely through the block 2 and is secured by anut 80. A rod -82 (Fig. 1) extends through the eye'of the bolt 78 and atits lower end is pivotally connected at 84 with `the vertically movablehead 2 of the compressor. spring 86 is arranged on the rod 82 betweenthe eyebolt 78 anda stop nut 87 on the rod 82 and above the eye-bolt 78is a stop nut 88. a stop screw 90 is threaded through a lug 92 on theframe 66 in position toV engage a stop projection 91 on the sleevemember 63 and limit upward movement of the arm 68 and inward movement ofthe arm 62.

The operation of the lingers 36 will now be understood by referenceparticularly to Fig. 1. It will be seen that as the head 2 will pushupon the eye-bolt 78 throughthe spring 86- 68 and will rock theconnected to the arm sleeve member 63, causing the arm 62 to move thelinks 46 to open the lingers and move them inwardly of the machine untilthe lugs 5() are located beyond the breast face of the, heel. This innerposition is determined by the stop screw 90 which limits movement of thearm 62 by engaging the lug 91, the screw, of course, being readilyadjustable to vary the inner position of the Further upward movement ofthe head 2 is permitted by compression of the spring 86. During downwardmovement of the head 2 no movement of the finger takes place until thehead is nearthe lower limit of its movement and the ejector has removeda heel from the mold. During the lirst part of the downward movement ofthe head the compression of the spring 86 is released, and finally thespace between the lstop nut 88 and the eye-bolt 78 is taken u allowingthe nut 88 to engage the eye-boltgS and elfect a movement of thev arm 68and arm 62 positively to withdraw the heel from the machine and topresent it in a predetermined position upon the table 52. The head 2, ofcourse, always returns to the same position and by 'adjusting the screw76 the elfectivelength of the arm 68 may be varied to cause the heel tobe presented on the table in predetermined but variable positionslongitudinallv of the heel.

The table 52 has a central hub 98 (Fig.

which is rigidly clamped in' a boss 100 formed on a supplemental frame102 bolted to the main frame 1 as shown. Arranged centrally of the hub98 is a short shaft 104 on the upper end of which (Fig. 7) is secured aspider 106. Pivoted to the spider at 108 are four pairs of jaws 110which constitute with the spider an endless carrier for the heels. Thespider 106 is moved intermittently by mechanism to be described topresent each pair of jaws in turn and permit them to dwell at successivestations A, B, C and D. The jaws of each pair are connected together forequal and opposite movement by interengaging teeth 112 and their closedposition is adjustably determined by a screw 114 having a threadedmounting on the spider and engaging a pin on one of the jaws. The jawsare held toward each other by springs 116. It will be noted from Fig. 3that each of the jaws is double, comprising a lower downwardly bentportion 111 which engages the surface of the table 52 and the portion110 which is attached by screws to the lower jaw 111 and extendsupwardly at a slight angle. The end portions 47 of the lingers 36, asthey are moved to force `the heel on to thetahle between the pair ofjaws located at station A, pass between the lower and upper portions ofthe jaws, the jaws separating if necessary against the spring 116 topermit the entrance of the heel to the heel engaging surfaces of thejaws and being preferably serrated or toothed securely to hold the heelin the position in which it is presented.

It has been found preferable to have the jaws open at the time the heelis presented between them since when the jaws are yieldingly heldtogether during insertion of the heel there is apt to be unequalresistance offered by the 'jaws with a consequent shifting of the heelin the plane of its toplift from the position determined by thetransferring fingers 36. Therefore, it is preferable to provide adjacentto station A means to engage a projection 206 on one of .the

ngers and cause the fingers to be opened while they are at rest atstation A. This means comprises a cam member 51 (Figs. 6, 7 and 12)which is adjustably fixed to the mold slide by screws 55. The member hasa downwardly and inwardly inclined face 53 which engages the projection206 during the downward movement of the mold slide and causes the jawsto open prior to the insertion of the heel between them. Furthermovement of the slide carries thecam face k53 beyond the projection,allowing the jaws to close upon the heel. The jaws then start to movetoward station B and the projection is out of the way of the cam 51during the next upward movement of the mold slide.

The amount removed from the heel in the breasting operation will dependupon its longitudinal position in the jaws and it is consequentlydesirable to provide a gage or stop for limiting the longitudinalmovementl of the heel. As shown, a plate 120 vis provided beneath eachpair of jaws, the plate having a V-shaped portion to engage the rear endof theheel. Each plate is arranged to slide longitudinally of the heeland is held in adjusted position by a screw 122 engaging a slot in thespider 106 and threaded into the plate 120.

Since each of the gage plates 120 should of the spider shaft 104, it isdesirable to provide means for adjusting the plates simultaneously andfor locating them at equal distances from said center. As shown, a camplate 113 is arranged beneath the spider for rotation relatively to thespider about the spider shaft 104. The cam plate 113 has four slots 119extending from its edge inwardly at an angle and each slot is engaged bya pin 119X on the corresponding gage plate 120. By loosening the screws122 and turning the cam 113 the gage Vplates 120 may be moved equallyand simultaneously in either direction lengthwise of the jaws 110. Forconveniently turning the cam 113 a pin 115 fixed thereto extends upthrough a slot 117 in the spider 106, the slot being curvedconcentrically with the shaft 104 and the pin 115 being used as a handlefor turning the cam. By moving the cam 113 to its limit in one directionthe open ends of the slots 119 will release the pins 119X and permit theplates 120 to be removed and others adapted for a different range ofheel sizes to be substituted therefor.

Adjacent to the lower end of the spider shaft 104 is mounted` in theframe 102 and in a bracket 121', a shaft 123 having at its lower end agear 124 meshing with a pinion 126 on a shaft 128 which is mounted inthe frame 102. On the shaft 128 is a gear 130 meshing with a gear 132 onthe shaft 9. The shaft 104 isvconneeted to the shaft 123 by intermittentgearing which may be of any suitable kind and is shown (Fig. 8) as ofthe Geneva type, the construction being such that a single rotation ofthe shaft 123 will cause a member 134 fixed to the shaft to impart aquarter revolution to a member 136 fixed to the shaft 104, it beingunderstood that the movement imparted to the shaft 104 will take placeduring a relatively small part, for example 900,-of the rotation of theshaft 123 and that during the rest'of the rotation the member 136 willbe locked from rotation and held in predetermined position with one pairof jaws 110 at the station A (Fig. 7) and another`pair at the station Bof that figure. The rotation ratio of the gear 132 tothe gear 130 is 1to 2 and the rotation ratio of the pinion 126 to the gear 124 is 2 to 1,and the relative timing of theA gearing set at the same distance fromthe centerproperly (xo-operate ment screw 167 Vmounted for` verticalreciprocation in the frame. An adjustable connecting rod 144 is pivotedto the knife slide at 146 and is carried at its lower end by a crank pin148 on a crank 150 secured to the shaft 128 so that a verticalreciprooation will be imparted to the knife slide as the shaft 128'rotates. A knife 152 (Fig. 5) is clamped in the knife slide by a screw154 and is adjustably held vertically by an abutment 156. When the slidedescends the knife operates to remove material from the breast end ofthe heel and is arranged to co-operate with' the edge of the table uponwhich ,uponl the heel. As shown the dwell at station B covers one and ahalf rotations of the shaft 128 and hence the knife makes two strokesacross the heel while the heel isat rest, the movement of the carrieroccurring -in the interval between the time when the knife leaves a heelon its Second lup stroke and the time when the knife reaches anotherheel on its next downstroke.

In order that knives of different curvesY maybe used for breastingtheheels and m-ay co-operate with the table to effect a shear cut withoutchanging the table, the portion of thetable upon which the -heel restsis made detachable as shown in Fig." 7. vThe table is provided withledges 158, -158 upon which a block 160 rests with its upper surfacefiush with the surface of the table. The front edge of the block 160 iscontoured to correspond with the curve of the knife and a screw 162 isthreaded through a lug on'- the table in position to engage the innerfend of the block 160 vto limit its inwardl movement and -to providemeans for adjusting the block so that its front edge will with thelknife. The blockI preferably has tongues 161 on its sides which engagegrooves in the table and the block 160 is held in the table by buttons164 held to the table by screws 166 and arranged to engage the tongues161 of the block 160. When the screws 166 are loosened the buttons 164may be turned up against pins 165 (Fig. 7 )l to permit removal of theblock 160. To take the thrust of the knifev against the block 16()an'abut- (Fig. 3) is threaded into the frame\102 beneath the block 160and from the mold on to -tilting of the heel occurs as it ,the heelrests to effect a shearcut into contact with the heel and may beadjusted vertically so that its head will bear against the lower. faceof the block and support it. f

While the lheel is being moved from its position over the mold to itsposition on the table the moldis moving downwardl and the plane of theto face of the mol is in the plane of the ta le only when the Amold isat the lower limit of its' movement. Therefore, tthe time when the heelp-asses the table the mold is somewhat above the table and a downwardpasses from the mold to thetable. If the jaws are not opened to receivetheI heel when'the heel is pushed into |them they may not allow thelower face of the heel tocome in firm contact with the table. Hence itis desirable to provide meansoto press the heel firml down upon thetable at the station A. Ff the jaws. are'open at' this time, as proposedabove, it is desirable to"'provide 'means to hold'the heel pressed downagainst the table in the position given to it 'by' the fingers 36 whenthe jaws close upon the heel. Accordingly a pressure 168 is arranged forvertical reciprocation in the, frame 66in position to engage the heelwith its lower outwardly bent end 169 and to press the heel firmly incontact with the table. Fixed at one end of the presser 168 -is alaterally extending arm 171 havin at its other end a sleeve 17 3arranged to s ide on an operating rod 175 which is pivoted to the headthe pin 84. On the rod 175 between the sleeve 173 and an adjusting nut17,7'is a stiff spring 179 and on the rod 175 between the sleeve is aweaker spring 183. Extending upwardly as acontinuation of the presser168 is a rod 185 guided in the frame 66 and having an adjustablestocollar 187 which engages the frame 66 to imit upward movement of thepresser.` As'pthe head 2 moves upwardly the spring 183 acts upon the arm171 to llft the .presser 168 as far as permitted by the .collar 187, andduring downward movement of the head 2 the presser is moved pressureapplied thereto through the, stili' spring'179. The timing is such thatthe presser is hfted during Ithe passage of the heel from station A tostation B. o.

It is desirable to clamp'jtheheel against the table during the actionofthe knife and for this purpose a clamp 170 is provided 173 and a fixedcollar 181 which has a downwardly ben-t end adapted 178 securedto theknife slide142. Duringl the downward movementof the knife the clamp 17 0is brought into contact with the v the pivot 184 a spring 186 heelbefore the knife engages it and the friction means 176 then slips on therod 172 during the cutting operation of the knife, the clamp beingrestored to its original position upon upward movement of the slide 142.

It may or heel is not positioned on the support 160 in proper positionfor a subsequent operation, for instance a heel for breasting, but isdisplaced slightly longitudinally or rotationally or both. Accordinglyrelatively power operated positioning members comprising the gage plate120 and a member ,180 are provided which act on the blank and cooperateto determine both its longitudiinal position and its rotational positionor orientation, that is, the direction of its longitudinal median line.As herein shown means is provided for insuring that the breast face ofthe heel will be positioned in proper relation to the breasting knifefor the breasting operation. Usually this position will be with thebreast face of the heel parallel to the edge of the knife. For thispurpose the member 180 hereinafter called a striker is provided which isbrought against the breast-end of the heel just prior to the breastingoperation. Preferably the portion of the striker which engages the heelcorresponds in shape to that of the compressed breast face of the heeland is arranged vertically so that it will strike the toplift portiononly of the heel which portion has usually the more uniform shape in acompressed heel. It is essential only, however, that the striker engagethe edge face of the blank or heel at points separated a substantialdistance laterally of the blank or heel. If the heel in the jaws isimproperly positioned the contact of the` striker 180 with the lower ortoplift portion of the breast face will cause the heel to moverotationally in a horizontal `plane until its breast face is in the samedirection as the striking face of the striker, and longitudinally untilit is against .the gage plate 120, if it does not already engage it, theresult being that the heel will then be positioned longitudinally sothat it will be.

breasted to the proper length and will have its breast face in properrelation to the knife for the breasting operation.. This proper relationis usually, in treating heels of the broad, low type shown, such thatthe breast face of the heel is parallel to the plane of action of theknife, that is, with its longitudinal median line substantiallyperpendicular to the plane of the knife. The striker 180 is mounted onthe lower end of a lever 182 having its upper end bent and pivoted at184 to the frame 140. Below is provided `between the lever 182 and theframe 140 to move the striker toward the heel. A locksometimes happenthat a blank.

links 188, 194 and the frame the breast end of the ing mechanism (Fig.4) is provided for holding the striker normally away from the heel andcomprises a link 188 pivoted to the frame 140 at 190 and having at itsother end a notch adapted to engage a pin 192 on the lever 182 and holdthe striker away from the heel in the position shown. A link 194 ispivoted at 196 to the frame 140 at one end and at its other end isconnected by a link 198 to the link 188. The pivots 190, 196 arepreferably provided with friction means to cause the links 188, 194 toremain in any position to which they are moved. These friction means maycomprise lock washers 197 placed between the 140 on the pivot screws190, 196 (Fig. 10). A detail of one of the washers 197 is shown in Fig.11. The washer is split and the ends bent somewhat out of line, one endbeing provided with a sharp lip 199 which digs into the part engaged byit and causes the washer to move'frictionally against the part engagingits opposite side. The washer will yield somewhat to pressure of thescrew which may be adjusted to secure the proper amount of friction. Aroll 200 is arranged on the knife slide 142 in position to engage thelink 194 when the slide is nearly in its uppermost position, the rollacting to lift the link 194, and, through the link 198, also the link188 to release the end of thatlink from the pin 192 and permit movementof the striker toward the heel. This movement, however, is controlled bytwo cams 202, 204 fixed to the lever 182 and having edges which engagethe roll 200. As the carrier and roll 200 move downwardly the roll willpass off the lower end of the cam 202 before the knife reaches the heeland allow the striker 180 to be actuated by the spring 186 against theheel to position it for the action of the knife. As the movement of theroll continues downwardly? it engages the cam 204 and pushes the lever182 outwardly sufficiently to allow the link 188 to come again intolocking engagement with the pin 192, then the roll 200 engages the link188 and moves it against the friction holding means into lockingposition, the parts remaining in this position until the return movementof the roll 200 has been nearly completed.

As has been described, the knife makes two strokes while the heel is inthe same position. The first cut removes material from heel by what maybe called a roughing cut.

of the knife across the breast face of the heel smooths up the breastface and is re-l ferred to as a finishing cut.

Upon the next intermittent partial rotation of the spider 106 the heelwill be carried to station Gand a new heel brought into station B forthe breasting operation. Upon The second passage fixed to the table 52land adapted to be en- 'an opening in gaged by the projection 206temporarily to' arrest movement of that jaw.y By reason of theinter-connection V112 between`l the jaws, the opposite jaw will becorrespondingly ,opened and the heel allowed to drop through Wheresuitable means may be provided to receive the heels. Upon the nextmovement of the spider 106 the projection 206 will ride off the member208 and allow the .jaws to be closed by ,their spring 116 before theyreach A station A again.

It is desirable so that it will yield after suflicient pressure has beenapplied to the projection 206 to open the jaws and also to provide meansto enable the projection to pass the member 208 without obstruction ifthe spider is turned back' wardly, as is sometimes necessary, as forin-r stance, when an abnormally thick heel is presented to thecompressor and the machine sticks and fails to go over. It is thennecessary to throw 0E the power and turn the machine backwardly .by handto enable the heel to be removed. Since the spider 106 is geared to thecompressor, the spider I. also must be turned backwardly and the jawprojection 206 will engage the member 208, and either that or the jaw bebent or broken if the member is not arranged to permit free rearwardmovement of lthe projection 206 past it.
